Applicationflled December 28,1906. Serial No. 349,856.

county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Gravity-Conveyors; and I do hereby declare the following to be a full, clear, and exact description of the invcntion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates particularly to so-calledfigravity carriers or conveying systems, and has for its object to improve the same in the several particulars hereinafterhoted.

The invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In "the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a plan view,

showing a portion of a gravity carrier or conveyer sections.

embodying the features of my invention. Fig. 2 is a side elevation of the parts shown in Fig. 1. Fig. 8 is a view partly in elevation, but chiefly in vertical section on the line a a, of Fig. 1, some parts being broken away. Fig. 4 is a view partly in elevation and partly in section on the line a x of 1, some parts being broken away. Fig. 5 is a transverse section on the line x x of Fig. 4. Fig. 6 is a perspective view, showing two abutting roller supporting rails separated from each other; and Fig. 7 is a detail in section illustrating a slightly modified form of one end of one of the rollers.

The numeral 1 indicates the roller supporting rails or bars which are spaced apart but rigidly connected at suitable intervals by transverse tie bars 2 and truss bars 3. In the straight sections of the track are mounted cylindrical rollers 4, and in the curved sections thereof are mounted tapered rollers 5, which rollers are above 1 the tie bars 2 and truss bars 3. The rails 1 are preferably formed in sections, which sections are connected by interlocking. joints, best shown in Fig. 6, by referof the lock lugs 67 and the face of the rail or bar from which theyare pressed, while the notch 9 is adapted to straddle the base of the lower lug 7, as clearly shown in Fig. 2, and thus rigidly interlock the two rail or bar The rollers 4 and 5 are connected to the rails 1 by ball bearingdevices which in this preferred ment include ball receiving sockets 10 that are forced .under pressure into seats or large perforations 10! formed in the rails 1. At the other inner extremities the ball receiving sockets 10 are provided with central perforated caps 11, the edges of which are clenched or bent over the outwardly flaring edges of the said sockets. The bearing balls 12 are confined in an annular run-way formed between said cap 11, the largest portion of the said socket 10, and an in-pressd annular shoulder 13 of the said socket.

The cylindrical rollers 4 are preferably constructed as best shown in Fig. 3, with out-turned end flanges 4, over which are bent the outer edges of roller heads 14. These roller heads 14-are centrally perforated to pass the body portions of trunnions 15, which trunnions have slightly reduced ends or journaled portions 16 and bevel heads 17 The bevel heads 17 of said trunnions are securely clamped between the inset portions of the A roller heads 14, and clamping plates 18 rigidly secured to said rollers by suitable devices, such as rivets 19.

The reduced journaled portions 16 of said trunnions project into the corresponding sockets 10 and runupon the balls 12 that are confined within said sockets.

The tapered rollers 5 are of novel construction. They edges thereof are bent over and around the said flanges 5", thereby holding the ends of the said tapered rollers in tlieproper form; The abutting in-turned longitudinal flangesv 5 have close joints and strengthenthe rollers at what would otherwise be their weakest points,

"to-wit, at their adjoining edges of-the rolled metal sheet which constitutes the body thereof. The arrangement of the trun'nions and ball bearing devices for the tapered rollers is the" same as that described in connection with the cylindrical rollers.

Fig. 7 illustrates a modification of the cylindrical roller in which the end thereof is provided with an in pressed annulargroove 20 between which and the inturned end flange 21 of which. roller is clamped a roller head made up of an annular plate 22 and a disk 23, which parts are connected by rivets 24, and as before described, hold the tapered heads 17 of the trunnion 15. The device described, while of small cost, is capable of being very quickly put together and is highly trunnions working in said sockets 10, and bearlng balls 2. The combination with supporting rails or bars and ball equipped sockets held in the seats formed therein, of rollers having heads interlocked with the end portions thereof, and headed trunnions interlocked with said roller heads, and journaled in saidball equipped sockets, substantially as described.

3. The combination with a roller having a flange at its end, of a roller head interlocked with the end flange of said roller, and a headed trunnion seated in and held by said roller head, substantially as described.

4. A roller comprising :1 rolled sheet metal body having flanged ends, and abutting longitudinally cxlcndod ode-vs. and roller heads interlocking with the end flanges of saal roller, substantially as described.

5. A roller comprising a rolled mclal body portion ll:l\'- ing abutting in-tnrned limgitudinally extended oda'cs and out-turned end flanges 5", and roller heads having; flanges bent or clenched around said end flanges 5". sub stantially as described In testimony whereof I :lfiix my signature in prcsvncc of two witnesses. l i
